Update January 20, 2015: here are links to the most recent reports and the cert-stage briefs in the second go-round for the case: Horne II "The World's Most Outdated Law" Crahses Headlong Into Takings.
It's not really the "Sun-Maid Girl," but rather the organization the trademark now represents, Sun-Maid Growers of California., who filed this amicus brief supporting the U.S.D.A. in Horne v. United States Dep't of Agriculture, No. 12-123 (cert. granted Nov. 20, 2012).
The brief makes one main point: the Hornes, as raisin "handlers" cannot assert a takings defense because they didn't have title to the raisins they claimed were taken, and thus lack standing:
Petitioners indisputably have no standing to assert a Takings defense to avoid civil liability, as handlers, for failing to set aside as reserve tonnage the raisins produced by other producers, because as handlers petitioners never took title to raisins produced by other producers subject to the reserve tonnage requirement. Instead, the marketing order transferred title directly from the producers to the Raisin Administrative Committee. If petitioners had complied with the reserve tonnage requirement with respect to the raisins produced by other producers, those producers, to the extent that petitioners' compliance with the marketing order would have effected a compensable "taking," would have been required to bring a claim in the Court of Federal Claims under the Tucker Act, 28 U.S.C. § 1491(a)(1).

Oh, we just can't wait for the oral arguments in this case.
In a footnote, the brief argues that the case could be dismissed as improvidently granted. See Brief at 7 n.3.
